Hi guys, I posted this before but it may be worth reading again.
Do you want to make an improvement in your cars performance that is
affordable, fits perfect, looks stock and WORKS GREAT?
This is what you can do.
Call Gordon Imports (ask about the cats) then order, one high performance
muffler, H/P "J" pipe, a gasket for the J pipe, three threaded studs with
copper nuts and an exhaust manifold gasket.
OK remove the exhaust manifold, if your lucky you can wiggle it out with the
muffler attached. Then what I did was took it as is to the NAPA machine shop.

They did two things 1) remove the studs "surface" that area and install the
new studs 2) have them "surface" that area where the manifold bolts to the
Now you want to polish the inside of the manifold. You can use a Dremal
or what you have but the smoother the inside is the better it will work.
Don't be afraid you can take a lot of metal out of the inside if you have the

time but the smoother the inside is the better it will work.
Now when you receive the J pipe and muffler for some reason they are not the
same size, just take them to the discount muffler shop of your choice and
have them stretch the J pipe so it will fit snugly into the muffler. Put it
back together, tighten the bolts on the manifold in the proper order. When
you reattach the J pipe take some flat stainless washers, grind one edge a
little flat and put them on the stud before the copper nut. You may not need
a clamp at the muffler if you have a good fit. If you do need a clamp get one

that is called a 360 degree clamp.
Hold on to your hat you are gonna notice a big difference in the performance
and your car WILL RUN A LOT COOLER.

PS if you follow those copper nuts with a couple stainless nuts on each stud
you will always be able to remove them in the further
